I've long asserted that the genres of horror and comedy are beholden to similar skill sets when it comes to their effective execution, primarily that the ability to build and release tension/expectations by means of either laughs or scares (or, in some cases, both) is absolutely essential.
If all Jordan Peele's debut film had going for it was a basic grasp of these skills (honed over years of fantastic sketch comedy on his and Keegan-Michael Key's "Key and Peele" run) coupled with the brilliant premise that is Get Out's central hook, he could have more or less coasted on that. But Peele shows up with a wicked, knowing smile, a thirst to play for keeps, and a surprising grasp of cinematic language for a first-time director.
And he absolutely CRUSHES IT. Get Out is a stone-cold modern horror classic, and best film of its kind since The Cabin in the Woods.
